From NeuroLex

A biological macromolecule that is composed of amino acids linked in a linear sequence (a polypeptide chain) and is genetically encoded. Proteins descended from a common ancestor can be classified into families and superfamilies composed of products of evolutionarily-related genes. The domain architecture of a protein is described by the order of its constituent domains. Proteins with the same domains in the same order are defined as homeomorphic (PRO:WCB)

*Note: Neurolex imports many terms and their ids from existing community ontologies, e.g., the Gene Ontology. Neurolex, however, is a dynamic site and any content beyond the identifier should not be presumed to reflect the content or views of the source ontology. Users should consult with the authoritative source for each ontology for current information.
